SANITARY BUTTER MAKING. AND MOLDING MACI-IIN'ET Specification of LettersPatent.

' Application filed February 19, 1912. SeriaINo. 678,694.

To all whom it may concern:

. Be it known that 1, CHARLES VOLKMANN, a citizen of the United States,residing in the city of Chicago, county of Cook, and State of Illinois,have invented a certain new and useful. Improvement in Sanitary ButterMaking and Molding Machines, of which the following is thespecification.

My invention has for its object to provide a machine which will make andmold the butter into bricks of suitable size and deliver it partiallywrapped without its being at any time necessary to touch the but- I terwith the hands, and has for its further object to provide means foradjusting the size of the mold to care for the variation and density ofthe butter being molded.

My means of accomplishing the foregoing may be more readily understoodby having reference to the accompanying drawings, which are hereuntoannexed and are a. part of this specification, in which: I

Figure 1 is a side view partly in section of my improved machine. Figs.2 and 3 are detail views of the molding mechanism.

Figs. 4: and 5 are enlarged detail views ofparts of the machine.

Similar reference numerals refer to similar parts throughout the entiredescription.

As shown in the-drawings, my machine consists of an upright receptacle 1which has mounted therein shafts 2 and 3. These shafts are provided withpaddles at and 5 which extend radially therefrom. A sprocket 6 ismounted upon the shaft 2 and sprockets 7 and .8 are mounted upon theshaft 3. A chain 9 extends from sprocket 6 to sprocket 7.

10 is a conveyer screw which is located in a horizontal cylindricalportion 11, the conveyer screw'being mounted upon a shaft 12, which maybe driven by any suitable power (not shown).

13 is a sprocket mounted upon the shaft 12 which carries a chain 14,which extends to the sprocket 8 mounted upon the shaft 2.

15 is a cut-off located in the cylindrical portion 11 for use during thechurning operation.

16 is a drain located in the lower part of the cylindrical portion 11.

17 and 18 are rollers mounted upon shafts 19 and 20, which are carriedby suitable bearings formed in the side walls of the machine. Theserollers 17 and 18 carry an endless belt or chain 21, which has securedto it at intervals the molding members 22, which'are formed, as moreclearly seen in the detail-views of a top or stamping member 23 and aside or cut-off member 2a. 25 is a receptacle containing water.

26 is a hose, which extends from a faucet 27 to a point adjacent thecutting off blades 24, being adapted to discharge the water on the face"of the mold.

The operation of the device is as follows: Cream is placed in thereceptacle 1. The shaft 12"is then rotated and through the medium;of-the chains 9 and 14: causes the rotation-ofthe' shafts 2 and 3, whichhas the effectof whirling the paddles & and 5 about rapidly. The motionat this time should be in the direction which will operate to give areverse motion to the conveyer screw. This causes it to force the liquidupward where it will be brought into contact with the paddles 4 and 5.It will be obvious that it is necessary during this part of theoperation to have the shut-off 15 closed. As soon as the butter hascome, the drain 16 is opened and the butter milk drained ofi. Saltywater is then placed in the-receptacle and the machine is again rotated,and the butter thoroughly worked when the drain 16 is again opened andthe salty water drainedoff. The shafts 12 and 6 are then rotated in thereverse direction. The shut-off valve 15"is1opened and the butter isforced outwardly through a nozzle 28 where it is brought in contact withthe face of the cut-off blade 24 and when the pressure becomessufliciently great it operates to move the chain or belt 21 and bringthe next adjacent cut-off down through the butter, the pressure of thebutter being great enough to cause it to receive any imprint which niaybe carved on the stamp with an opening 35 which is above a slide 86,which leads to a table, (not shown) or any other convenient storageplace.

The operator stands by the machine and places one of the blanks ofcardboard, from which the boxes are folded, together with a sheet ofparaffin paper on the top of the flaring portion of the metal box 30. Asthe butter drops from the mold it strikes the cardboard blank andparaliin paper on top of the metal box pressing it down into the metalbox thereby making the folds in the sides of the box. Then the belttravels down until it reaches the opening when the box drops out on tothe slide 36 whence it passes along the slide to the table or workbench, when the wrapper has simply to fold the ends and the butter iswrapped, the entire operation having been performed without the butterat any time being touched by the hands of the operator.

In order to avoid the possibility of the butter sticking to the mold, Iprovide a water supply 25 so that through the medium of the hose 26 astream of water can be kept constantly on the cut-otl blades and stamps,immediately prior to the mold receiving the butter, so that it alwaysslides oil of them without the least difiiculty. The means of adjustingthe size of the molds is more clearly seen in the detail views in whichI provide a set screw 33, mounted in the back of the stamp and extendinginto the chain or belt 21. It will be obvious that by operating thisscrew, you can vary the distance between this stamp and belt, therebyvarying the volume of the space into which the butter is to be held. Onthe back of the stamp are mounted two screws 37, which pass throughslots 38 formed in the base of the cut-off blades at. It will be obviousto persons skilled in the art, that by loosening these screws thecut-off blade can be moved so as to make the mold either larger orsmaller. lVhen it is of the right size to give the required weight, thescrews 32 are set up tight and serve to hold the cut-off blade rigidlyand securely in position.

Having described my invention, what I regard as new and desire to secureby Letters Patent is:

1. In a device of the character described the combination oi areceptacle having a plurality of agitators therein, a cylindricalportion extending from the receptacle, having a drain on its lowerportion, a conveyer mounted therein, a shut-oil locatedin saidcylindrical portion, a nozzle secured to said cylindrical portionprovided with a rectangular opening, an endless belt carried by suitablebearings adjacent the said nozzle, a plurality of molds secured to saidbelt, the sides of which operate as cut-off blades.
